I've got a function which takes two strings and should return 
them as a ubyte[] with additional zero bytes in between and 
around. This works:

    ubyte[] convert_string_pair(string first, string second)
    {
        auto b = new ubyte[](0);
        b ~= 0x00 ~ first ~ 0x00 ~ second ~ 0x00;
        return b;
    }

But I think it would be more elegant to do it in a single return 
statement, but unfortunately this does not work:

    ubyte[] convert_string_pair(string first, string second)
    {
        return 0x00 ~ first ~ 0x00 ~ second ~ 0x00;
    }

The reason is, that this expression creates a string and not a 
ubyte[]...

Try:

   ubyte[] convert_string_pair(string first, string second)
   {
       return cast(ubyte[])(0x00 ~ first ~ 0x00 ~ second ~ 0x00);
   }
